postfix не будет обращаться к тому же домену с gmail

Я использую приложения для малого бизнеса postfix и gmail

Кажется, он отлично работает для отправки электронной почты на внешние домены, но не работает при попытке отправить по электронной почте с того же домена

Так, например, info@mysite.com отправляет на john@yahoo.com без проблем Однако info@mysite.com не отправляет на chris@mysite.com

Вопрос в том, есть ли проблема с моим файлом конфигурации postfixc?

# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname
